T his providing of the rightangularly extending hinge knuckles l t on the lower end of the platen lladapts said platen to be held and remain in upright position as shown inFig. 3 without requiring any auxiliary fastening means. This is due toti 0 fact that these laterally extending knuckles lt pivotally connectsaid platens with the pintles 13 in ollset relation, so that when theplaten is swung upward it will be olt center and thus he held by gravityin this position. Moreove1.',-this a 'rangement oi the hinge knucklesand the connection with the two platens provides for the holding of theplat-ens in upright position when they are con ected together to receivethe molten metal as shown in Fig. 2 and it also provides for one plateor both standing upright without the use of any locks 0r latches.

In Fig. 3 the platens are shown in open position with the caststereotype shown on the bottom platen. This position is also what may betermed the make-up' posh tion, which is the position occupied by theplatens when preparing them for the reception of the molten metal beforethe castings are stereotyped. lhe platens are held in spacedrelationship and the molten metal is confined in the casting chambertermed between the platens by of any desired construction. In theembodiment illustrated. the gauges comprise longitudinally extendingbars 3 and 32 and a transversely attending bar 333. These bars are heldtogether by the clamping action of the two platens and the bars 3 1. and32 may he moved toward or away from each other so that castings ofvarious widths may be made.

The matrix (not shown) is placed against the upper .tace ol the lowerplaten l and the gauge bars nl, 32 and 33 are placed thereover in thedesired positions. The bars Ill and 32 are provided. at their outer endswith handles 34- which project beyond the platens when in operativeposition a d may be used to facilitate the manipulation of the connectedplatens, as wet as .i'or the manipulation of the bars in relation toeach other.

Then the matrix and the gauges are properly positioned the upper platen11 may be swung down against the upper faces of the gauge bars withoutcausing any movement of the lower platen and without causing the bars toshift on the platen. It is understood that when the platens 10 and 11with the matrix are arranged as described and lock d together by thelocking elements 19, a casting chamber will be provided between the bars31, 32 and the opposed faces of the matrix on platen 10 and over whichis arranged platen 11, the transverse bar 33 forming a bottom for saidchamber. The opening to receive the molten metal is formed at the upgerend of the connected platens, as is clearly seen in Fig. 2.

The locking elements 19 are preferably constructed in the form of quickacting clamps ot the construction shown in the drawings and eachcomprises a threaded rod or bolt 35 pivoted at one end in the notch 18of the platen 10 and adapted to swing downward and upward to permit theplaten 11 to be positioned over or released from the platen 10. his rod35, when the platen ll is swung down over platen 1.0, enters one of thenotches l8 at the sides ol the platen 11 and thereby holds the platensagainst sliding movement relative to each other and when the sleeve 36which is threadedly mounted on the rod 2-3.3 is screwed. down intoclamping engagement with the outer face of the platen H, the two platensare securely locked together and held inst swinging toward or away fromeach other. Operating handles 37 for the sleeves 36 are shown passedtransversely therethrough for turning the sleeves into clamping orreleasing position, providing the necessary leverage to securely clampthe platens in operative positions.

After the platens have been lot-.ted together with the matrix betweenthem in the manner above descibed, they may then he swung from thehorizontal position shown in Fig. l to the vertical position shown inFig. 2, or vice versa. The metal pot or receptacle is pivotally mountedon the standards the. pivot or trunnion 2t being shown located forwardOil the center of the receptacle so that said receptacle will alwaysretain its position when not in use, and yet pern'lit it to be freelyswung downward to bring the spout- 22 thereof into register with thefunnel 223 which is positioned to register with the open upper end ofthe casting chamber between the platens when the platens are in upswungposition, as shown clearly in Fig. 2.

The funnel 223 is shown mounted on a cross plate or bar 40 which. ismounted between the standards 5 and has laterally extending ends 4;].bolted to said standards, as shown clearly in Figs. 2 and 3. This funnel23 is open throughout its length at the inner side thereot', as shown atill to adapt it to receive the spout 22 when the receptacle 20 is tiltedon its t nnnions to pour the metal, the walls of said tunnel operatingas guides for the spout.

An operating handle or lever 25 is preferably secured to one end of thevessel 20 to facilitate the tilting thereof for placing it intooperative and inoperative position. The depth of the funnel from itsopen face to its rear wall is such as to take care of any variation inthe position of the pouring spout 22 in its travel during the differenttilting stages of the pot 20 during the pouring operation. The outer orrear wall of the funnel is curved at its lower end as shown in Fig. 2and operates to deflect the molten metal from the spout away from themat and direct it against the platen 11 thereby avoiding burning of themat by contact with the hot metal. It will thus be seen thatthe enteringho-t metal follows the rear side of the casting chamber to the bottomwhere it spreads and rises equally at all points causing any dross orforeign matter to float upward and thus produce perfect castings. Thisfeature works equally well when the pot is quite full and the pouringspout 22 is high in the funnel as it does when the pot is nearly emptyand the spout is low.

l rates 26 and 27 are preferably arranged at the ends of the receptacle2() being bolted or otherwise secured to the standards 5 and which aredesigned for retaining the heat beneath the receptacle and therebyfacilitate the rapid melting of the metal which is to be used in pouringthe casting. It will thus be seen that the funnel 223 may be arranged inclose relation. to the metal vessel 20 so that when the vessel is begunto be tilted the spout 22 thereof will pass immediately into the funnelthrough the slot 24 therein and thus avoid all possibility of anyspilling of the molten metal.

It will thus be seen that a strong Simple apparatus is provided and onein which the platens will be gravity held in position for the pouring ofthe metal avoiding the necessity of using any auxiliary fastening meansfor this purpose, and which provides also for the retention of the backor upper plate in upright position when separated from the lower plate.

Vithout further description it is thought that the features andadvantages of the invention will be readily apparent to those skilled inthe art, and it will of course be understood that changes in the form,proportion and minor details of construction may be resorted to, withoutdeparting from the spirit and scope of the claimed invention.
